{"title":"Cold ancestors, bigger predators: maternal and transgenerational temperature effects on Orius laevigatus body size","authors":"Ana Belén Abelaira, María del Carmen Reche, Amador Rodríguez-Gómez, Virginia Balanza, Pablo Bielza","doi":"10.1007/s10340-026-02073-7","DOIUrl":"https://doi.org/10.1007/s10340-026-02073-7","url":null,"abstract":"Developmental temperature strongly affects insect body size, a key trait for the performance of predators used in augmentative biological control. The anthocorid <jats:italic>Orius laevigatus</jats:italic> is widely released against thrips in greenhouse crops, and larger individuals show higher fecundity and predation capacity. Here, we analyze how thermal history across generations shapes adult size in this predator, combining genetic improvement and phenotypic plasticity. We compared two cold-tolerant lines of <jats:italic>O. laevigatus</jats:italic> , previously selected for enhanced performance at low temperature, with a commercial strain. Lineages were reared for four successive generations under combinations of 15 and 26 °C, and pronotum width of adults from the last generation was measured as a proxy of body size. Cold-selected lines were consistently larger than the commercial strain across all treatments, confirming a strong genetic component to size. Developmental temperature in the last generation had the largest effect, with individuals reared at 15 °C being larger than those reared at 26 °C. In addition, exposure of parents, grandparents, and great-grandparents to 15 °C increased the size of descendants, revealing a clear but gradually declining transgenerational effect. However, multiple consecutive cold generations did not further increase size and could even reduce it. These results show that combining cold-selected lines with strategically timed cold rearing can generate larger predators without permanently slowing mass rearing, although prolonged exposure to low temperature may be counterproductive.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"42 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148432130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paulin, György Csóka","doi":"10.1007/s10340-026-02063-9","DOIUrl":"https://doi.org/10.1007/s10340-026-02063-9","url":null,"abstract":"The oak lace bug (OLB, <jats:italic>Corythucha arcuata</jats:italic> ), originally native to North America, is a rapidly spreading invasive insect in Europe. Since its first detection in Italy in 2000, it has been reported in 25 countries, with its expansion largely driven by human-mediated dispersal. OLB is a multivoltine species, and its spread is further facilitated by the fact that nearly all Eurasian deciduous oak species are potential hosts, and it can also feed on several other woody plants. As a result, OLB has the potential to occupy up to 30 million hectares of oak forests in Europe and even more in Asia. Some studies indicate that OLB has significant negative effects on oaks and associated ecosystems. It reduces photosynthetic activity in oaks, impairs seedling growth, and there are implications that it also decreases fecundity. These impacts weaken tree health and could threaten the diverse communities of herbivores dependent on oaks. OLB may also influence other ecosystem components, such as leaf litter, surface waters, and even human health. Although its population dynamics are influenced by climatic conditions, current evidence suggests that European winters do not strongly constrain its spread. Various chemical control methods and some biological control agents have been tested, but no effective and environmentally sustainable management strategy is currently available. The egg parasitoid <jats:italic>Erythmelus klopomor</jats:italic> is the only known specialist enemy of OLB in North America and represents a promising long-term control option. However, further research on its behavior and host range is necessary before considering its intentional introduction to Europe.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"16 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148432163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to identify the insecticidal effectiveness of five major essential oil components and their binary mixtures against <italic>Metopolophium dirhodum</italic> (Walker) (Hemiptera: Aphididae), an important cereal pest. For the tested compounds, probit analysis was employed to estimate LC₅₀₍₉₀₎ at 2.32 (8.99) mL L⁻¹ for citral, 1.07 (4.65) mL L⁻¹ for eugenol, 0.91 (2.47) mL L⁻¹ for geraniol, 2.65 (11.74) mL L⁻¹ for geranyl acetate and 2.20 (7.51) mL L⁻¹ for terpineol. Phytotoxicity for experimental plants of <italic>Triticum aestivum</italic> L. was proven for citral, eugenol and geranyl acetate at concentrations equalling the estimated LC₉₀ for <italic>M. dirhodum</italic>. Geranyl acetate was shown to be an important synergist with all the other tested compounds. The best insecticidal effect was observed in the binary mixture of geranyl acetate/terpineol (1:1 ratio), for which the LC₅₀₍₉₀₎ was estimated at 0.97 (3.72) mL L⁻¹; at the same time, no phytotoxicity to the experimental plants of <italic>T. aestivum</italic> was observed. This binary mixture also turned out to be very friendly to the larvae of <italic>Aphidoletes aphidimyza</italic> Rondani (Diptera: Cecidomyiidae) and <italic>Chrysoperla carnea</italic> Stephens (Neuroptera: Chrysopidae), two important aphid predators.
